Title: Packaging
IPC: B65B11/54
Filed: 1941-06-26
Abstract: 550,980. Packing. WINGFOOT CORPORATION. June 26, 1941, No. 8061. Convention date. Aug. 2, 1940. [Class 94 (i)] Relates to a method of wrapping an article in a sheet of material which is rendered plastic and elastic by heat, such as rubber hydrochloride or polyvinyl chloride. The invention consists in heating the sheet material to a temperature at which it is both stretchable and elastic, stretching the heated sheet, and then wrapping the stretched sheet around the article. The invention may be carried out by gripping opposite edges ot the sheet 1, Fig. 1, in clamps 2, 3, one or both of which are slidable along rods 4. The clamped sheet is heated to a temperature suitable for . stretching preferably to a temperature at which the material will stick to itself. The clamps are then moved apart to stretch the heated sheet, an article 5 placed on the stretched sheet, and the clamps are brought together, as shown in Fig. 3, to press the edges of the sheet together and seal them, the sheet forming an open ended tube around the article 5. The sealed edges may be trimmed by a knife inserted through a slot 8. The clamps are then released, and the ends of the tube of material are closed or folded by any suitable method while the material is still hot. As the material cools, it contracts and causes the wrapping to conform closely to the shape of the article. If desired, part or whole of the sheet may be cooled before wrapping around the article to control the subsequent contraction.

Filed: 1961-03-07
Abstract: 989,871. Hooks. DUNLOP RUBBER CO. Ltd. March 1, 1962 [March 7, 1961], No. 8191/61. Heading F2H. A hook assembly for use in lowering a life-raft from a ship's davit and releasing it as the water takes the load, has a hook 1 pivoted at j between two bolted side plates (of which one 4 is shown) and bearing a pivot h for twin tieplates 16 joined at their other ends by a pin g which can slide in guide slots 15 in the plates 4 to permit pivotal raising and withdrawal of the hook 1 (from a yoke 4a and a load shackle therein) by a spring 17; this occurs, Fig. 4 (not shown), when the load is so light that friction between its shackle and the hook 1 is overcome by the spring and when the pin g is free, as shown, from the hook end 13b of a pivoted detent 13. When the hook is bearing full load, Fig. 1 (not shown), the pin g is detained by the end 13b but when the load is partly lightened, the hook assembly rises until the bottom of an eye member 2, by which the assembly is suspended, meets, as shown, the bottom of an elongated hole in a bearing plate 3 secured between the side plates 4, while a heel 11b of a boot-shaped member 11 trips the detent 13 by contacting its tongue 13a. The hook is then ready for release when the load is further lightened. The suspension eye 2 is secured by a turnbuckle 7 and pivot a to a lever 8 pivoted at b to the plates 4, the other end of the lever being loaded by a spring S so that full load on the hook stretches the spring by lowering the hook assembly and the pivot b until the eye 2 meets the top of the hole in the plate 3. The boot 11 is pivoted at e to a lower extension of the lever 8, being held by a spring 12 against an edge 8c until, from the position shown, the pin g rises, as the load is released, to strike a toe 11a to free the tongue 13a and permit the detent 13 to turn anticlockwise about its pivot f and so return to its full load position. Rollers on the ends of the rising pin g also raise a U-shaped lever 18 about its pivot I (although the lever may be loaded by a spring to rise whenever released). To lock the hook on to a new load, the handle 18 is depressed and the downcoming pin g rides on an edge 13d of the detent to depress it and permit the heel 11b of the boot 11 to move over the detent tongue 13a to its pre-trip position and the middle of the pin g to engage itself in the detent hook 13b.
